8:17 PM ì¬ webwork.uoregon.edu AT&T令 vious Problem List Next (1 point) Let f(x) =-z4-2x3 + 9x-8 Find the open intervals on which f is concave up (down). Then determine the r-coordinates of all inflection points of f is concave up on(-inf, inf) the intervals IS concave 2. down on (-inf,inf) intervals The inflection points occur at x= 3 Notes: In the first two, your answer should either be a single interval, such as (0,1), a comma separated list of intervals, such as (-inf 2), (3,4), or the word "none" In the last one, your answer should be a comma separated list of r values or the word "none".
